Volley的使用

mQueue = Volley.newRequestQueue(mContext);
StringRequest stringRequest = new StringRequest(Method.POST, url,
new Response.Listener<String>() {

@Override
public void onResponse(String arg0) {
Log.i("QuestionList", arg0);
ToastUtils.showToast(mContext, "贷款申请成功");
}

}, new Response.ErrorListener() {

@Override
public void onErrorResponse(VolleyError arg0) {
Log.i("QuestionList", arg0.toString());
}
}) {
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<String, String>();
headers.put("Authorization", "Bearer " + Constants.access_token);
return headers;
}

@Override
public Map<String, String> getParams() {
// 在这里设置需要post的参数
Map<String, String> paramsMap = new HashMap<String, String>();
paramsMap.put("farmerId", farmerId);
paramsMap.put("contact", uploadName);
paramsMap.put("contactNum", uploadPhone);
paramsMap.put("seedType", cropId);
paramsMap.put("weight", uploadWeight);
paramsMap.put("weightUnit", "");
paramsMap.put("hopeSaleDate", uploadTime);
paramsMap.put("hopeSaleAddress", uploadAddress);
return paramsMap;
}
};
mQueue.add(stringRequest);
